摘要
光通讯作为无线通信领域的新兴通讯手段具有广阔的研究前景,其系统信号感知方法的研究是光通讯领域的重点问题。现阶段光通信的信号感知方法存在识别效果不佳、受噪声干扰大的问题,为了解决方法中存在的问题,提出基于区块链技术的光通信系统信号智能感知方法。首先,使用结合重构方法的傅里叶变换采集光通讯信号;其次,基于区块链技术对采集到的调制信号实行分布式存储与读取;最后,基于支持向量机方法完成光通信系统信号的智能感知。实验结果表明,所提方法的光通讯系统信号感知识别正确率更高,受噪声影响更小,具有较好的实际应用价值。
As an emerging communication method in the field of wireless communication,optical communication has broad research prospects.The study of its system signal perception method is a key issue in the field of optical communication.At this stage,the signal perception method of optical communication has the problem of poor recognition effect and great interference with noise.In order to solve the problems in the solution,the light communication system signal intelligent perception method based on blockchain technology is proposed.First of all,use the Fourier transformation of the Four Dege to collect optical communication signals with a combination of reconstruction methods.Intelligent perception.The experimental results show that the method of signaling the optical communication system mentioned by the method is higher,the noise is smaller,and it has better practical application value.
